NOTE:
The time between each FLASH address change, or the time between
the last FLASH address programmed to clear the PGM bit, must not
exceed the maximum programming time, t
Programming and erasing of FLASH locations cannot be performed by
code being executed from the FLASH memory. While these operations
must be performed in the order shown, other unrelated operations may
occur between the steps. Do not exceed t
